I decided to post this now that it's been four days and nothing has changed. When I check my ad reveiew center for targeted ads, I'm getting 12 or more new advertisers UNRELATED to my website (teeth whitening, spa treatments, etc.), each day. I'm spending a lot of time checking and blocking these ads from showing. Is anyone else seeing this since Nov. 1, or is it my issue?

I just looked in mine out of curiosity - its not something I do often - and was surprised that I have duplicates of the same advertiser over and over - one dating advertiser repeats like a dozen times. Not useful if I were actually serious about going through and approving or blocking advertisers.

I've been getting ads in Chinese, Russian, you name it! I have no idea what a lot of the ads are. And I've been getting about 10 pages of ads a day to approve or disapprove. This has never happened before! It's ready to drive me nuts. NUTS I tell ya!

WARNING: If anyone still has 'Run Ads immediately' checked, put that on Hold for 24 hours. I just found 4 advertisers whose pages are 'Malware effected' (warning given by Chrome browser) in the review list. Now this is not a joke Google

Does anyone recall when Google introduced all these Certified Ad Networks to AdSense publishers? If it's been a few months now and there aren't many people experiencing a noticeable increase in revenue as a result, then what's the downside of just blocking them all?

This is so bad now, I'm go to rem,ove targeting from all of my channels until this is fixed, my eCPM and CTR are crap already because of this, so why allow page targeting when this is what's killing me.

@frakilk, my CTR and eCPM went way down as well. It's been over an hour since I removed targeting, and I haven't received any new ads...yet, so I'm hoping this is the solution. Also my eCPM shot up, and my CTR went up slightly. Now I wait.

This definitely seem to be affecting many! But only a few notice them as there are not many keen followers of what gets displayed as ads on their sites.

Here is one more thing that i notice.It is blocks chosen as "text only" are affected the most than the "text/image" blocks. How about others? Are you noticing the spam in both and where do you see the most?
